We present a case of a 39-year-old woman presenting to the emergency department with persistent vaginal bleeding with myoma and endometrium thickness. The qualitative urine human chorionic gonadotropin (hCG) showed positive result, however, the quantitative serum hCG had negative result. The negative serum hCG result suggests that the false-positive result was not caused by elevated circulating hCG. ⋯ On the basis of our findings, the false positive pregnancy test was not caused by hemoglobin. It is important to confirm a suspected false-positive urine hCG test using a quantitative serum hCG test. Although it is not certain the mechanism for false positive reaction in this peculiar sample, the ACON urine hCG one-step pregnancy will occasionally yield a false-positive result in this class of patients.

We report a case of a 49-year-old woman with a ruptured liver and spleen found at autopsy, which may have been related to the use of a mechanical cardiopulmonary resuscitation (CPR) device (AutoPulse, ZOLL Medical Corporation, Chelmsford, Mass). She was admitted because of an out-of-hospital resuscitation, and under the suspicion of a pulmonary embolism, a thrombolytic agent was administered. ⋯ The evidence for improved outcomes after the use of a mechanical CPR device during resuscitation is still scarce. To prevent the unique complications reported here, regular checking of proper position of the chest band during resuscitation is advised.

Necrotizing fasciitis is a severe life-threatening soft tissue infection characterized by rapidly spreading necrosis of the fascia and the subcutaneous tissue. Mortality as a result of streptococcal necrotizing fasciitis has been associated with the presence of hypotension, streptococcal toxic shock syndrome, or bacteremia in the literature. These infections are rare in children, and the diagnosis should be considered in the presence of any soft tissue infection presenting with signs of toxicity and marked wound edema. ⋯ A high index of suspicion is most important when there is a paucity of specific cutaneous findings early in the course of the disease. The diagnosis of necrotizing fasciitis should be considered for any individual who has unexplained limb pain. Even for treating patients with minor trauma, the emergency department physician should keep a high level of suspicion of the possibility of a fatal outcome from the subsequent invasive streptococcal infection.

The aims of this study were to assess the diagnostic value of D-dimer in patients with suspected acute mesenteric ischemia (AMI) and to evaluate the correlation between D-dimer levels and the severity of bowel necrosis. ⋯ Detection of serum D-dimer could not help to differentiate patient with AMI from those with non-AMI. We did not find a correlation between serum D-dimer levels and the severity of AMI. However, measurement of D-dimer levels can be of value for a small decrease in the likelihood of AMI, when the result is low.

Case Reports
Transdiaphragmatic repositioning of the heart in the setting of emergency laparotomy after blunt trauma.
Cardiac luxation after blunt trauma is a rare condition that carries a high mortality rate. We report a case of a left pericardial rupture with partial dislocation of the heart into the left pleural cavity and cardiac strangulation in a polytraumatized patient after a severe motor vehicle accident. This case is of special interest because the patient not only had cardiovascular compromise but was also actually in cardiac arrest and being resuscitated when an emergency repositioning of the heart through the diaphragm in the setting of damage control laparotomy restored circulation. This report stresses the need for a high index of suspicion for accurate early diagnosis of pericardial rupture.
